Technical Specifications Category Specification Model Type 1301F-1 Type Self-Operated Pressure Reducing Regulator Function To reduce a higher, variable inlet pressure to a stable, lower outlet pressure. Power Source Self-Operated (Uses energy from the process fluid) Body Style Globe Valve Body End Connections Flanged (typical for "F" designation, e.g., ANSI Class 125 or 150). Orifice Size Defined by the "-1" code, which corresponds to a specific diameter. Outlet Pressure Range Defined by the "F-1" configuration. This is a field-adjustable range, but the spring is selected for a specific span. Example ranges could be 5-20 psig or 10-50 psig. The exact range must be confirmed from factory data sheets. Maximum Inlet Pressure Typically up to 400 psig (28 bar) for standard bodies. Flow Coefficient (Cv) Determined by the "-1" orifice size. This value is critical for sizing the valve for the application's flow rate. Temperature Range Standard with Buna-N diaphragm: -20°F to +180°F (-29°C to +82°C). Materials of Construction Body: Cast Iron (standard), Ductile Iron, Brass. Trim (Plug/Seat): Stainless Steel (standard). Diaphragm: Buna-N (standard).
